[1] 50% (mass fraction) solution in butyl acetate and ethanol, butyl acetate and ethanol account for 85% and 15% respectively.

[2]50% resin solution of ethanol, solution temperature remains 25°C when viscosity is tested.

Solubility:

Aldehyde Resin KLT series are soluble in almost common paint solvents such as aromatic hydrocarbons, alcohols, ketones, esters and so on but insoluble in water. Its solubility in nonpolar solvents such as mineral oil, aliphatic hydrocarbon, alicyclic hydrocarbon is limited.

Application:

KLT aldehyde resin has excellent compatibility and solubility, applicable for various sorts of coatings/oil ink formulas; Effectively to improve coating film’s yellowing resistance, gloss, adhesiveness, hardness and gloss.
Good pigment and filler wetting function, applicable for all purpose colorant’s grinding resin thanks to its low viscosity while being dissolved or melted
KLT Non-Benzene and KLT A101 NonBenzene especially applicable for environment-friendly coatings/oil ink formulas thanks to their being free of benzene, toluene and xylene.
Dissolved into solvents to prepare 50% resin liquid, then added it into coatings/oil ink formulas. Generally adding percentage is 5-30% of the formula’s total mass.
